    -3x + 4y = 12

    get into y = mx +b form

    -3x +3x + 4y = 12 + 3x

    4y = 3x + 12

    4y/4 = (3x+12)/4

    y = 3/4x + 3

    y = mx +b, where m = slope, b = y-intercept

    SO our slope is 3/4, and our y-intercept is (0, 3)

    Put into form y = mx + b

    - 3x + 4y = 12

    4y = 3x + 12

    y = 3/4x + 12/4

    y = 3/4x + 3

    Slope is 3/4 and y intercept 3

    -3x + 4y = 12 =>

    4y = 3x+12 =>

    y = (3/4)x + 3

    y = a*x + b , where a is the slope and b is the y interceptor

    You should be able to figure it out know ; )

    Write as an equation:-

    -3x + y = 12

    y = 3x + 12

    slope = 3

    y intercept at point (0,12)
